Body Measurement Fetish ?

I once read about a fetish practiced in Japan, in which people take extremely detailed measurements of another person's nude body including detailed measurements of genitals such as size of clitoris or length of foreskin etc. I tried it with a couple of partners since then and it was pretty erotic. Has anyone heard of this, or tried it, or think it would be fun to try being measured that way?

Play doctors have been doing things like that for a long time. I would love to develop a sex machine and a part of the R&D have to take a lot of detailed measurements. You go get me the room full of naked co ed's and I will go and get my calipers...
